Interrelationship between Diabetes and Periodontitis- A Review

Abstract

Evidence for the link between periodontal disease and several systemic diseases is growing rapidly. Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life causing morbidity and mortality. Periodontitis, one of these complications, is a chronic infection associated with substantial morbidity in the form of tooth loss and that affects the quality of life directly. The association between diabetes and inflammatory periodontal disease has been studied extensively. The relationship between these two conditions appears bidirectional. The presence of one condition tends to promote the other and the meticulous management of either may assist treatment of the other. It also provides a perfect example of a cyclical association, whereby a systemic disease predisposes the individual to oral infections, and once the oral infection is established, it exacerbates the systemic disease. This review focuses to explain the interrelationship
between the two based on information in the literature and the potential common immunoregulatory connections involved, exploring the mechanisms through which periodontal infection can contribute to the low-grade general inflammation associated with diabetes.
